jenkinsflow's Issues

Put jenkinsflow to pypi

It would be nice if jenkinsflow would be available in https://pypi.python.org

Just to let you know, I created quick and dirty implementation of new invocation type: invoke_delayed. In this invocation the job is not going to call jenkins for Job object till right before it will be invoked. This is to be able to call a job, that is being created by a job executed within pipeline.

Once I finish with it, I will create pull request.

Also, take a look at jenkinsapi, there is a new way to invoke jobs has been introduced recently.

subprocess dependency

Hi, Lars

I have RHEL 5.4:

lsb_release -i -r
Distributor ID: RedHatEnterpriseServer
Release:        5.4

when I try to python setup.py install library subprocess32 fails to install due to C compilation issues. That library only used in tests and in one optional file that I am not going to use. So I have to modify setup.py to remove that dependency...

Is it possible to remove that dependency?

Thanks!

Pipeline jobs executed in parallel end up running the same build

I created simple test pipeline and execute two instances of it in parallel. When job is scheduled by one pipeline, but job status is QUEUED second pipeline will "attach" to that build instead of scheduling another build. Once job has RUNNING status - both pipelines will report the same build number.

I would expect that if build is queued the pipeline still try to schedule another build.

Thanks!

More information about installation is needed

Hi,

It is not clear how to install this plugin into Hudson/Jenkins.

Is it even a plugin? If so - Hudson .hpi/Jenkins .jpi needs to be provided and plugin needs to be registered with Hudson/Jenkins plugin repos.

Minor issue with Jenkins.init in specialized_api

Hi,

Coming from use of jenkinsapi, I expected that Jenkins.__init__ parameters would be in the same order as ones in jenkinsapi. Apparently they are not. I think it would be a bit better to have the same order of params as in jenkinsapi: url, username, password and extra params would go next.

Shebang in .py files

Lars,

I think it is bad to add this #!/usr/bin/python into .py files. Some people don't have python in that location and some may have Python 2.4 in there.

Just a thought.

Timeout

Hi!

In my Jenkins 1.484 I created 3 simple jobs: flow-1, flow-2 and flow-3. Each job does 'uname -a'.

I created simple flow:

    with serial(api, timeout=70, job_name_prefix='ADMIN-', report_interval=3) as ctrl1:
        ctrl1.invoke('flow-1')

        with ctrl1.parallel(timeout=20, report_interval=3) as ctrl2:
            ctrl2.invoke('flow-2')
            ctrl2.invoke('flow-3')

        ctrl1.invoke('flow-1')

And this happened:

Passing "token" parameters in "invoke"

Hi,

It doesn't work in latest Jenkins.

According to Jenkins Docs job cannot be triggered by issuing GET on $job_name/build URL. Instead, it now requires GET with token parameter. That parameter is set in additional setting in job itself and jenkinsapi will have to pass this token for the job. This is already supported by jenkinsapi, but here is no way to pass that token in jenkinsflow. Any parameters to invoke function will be treated as job parameters and in result jobs will fail to execute.

There shall be a way to pass token parameter as special one.

Is it possible to add timing information to final report?

Hi, Lars

Somebody asked me to give details about job execution times in jenkinsflow pipeline. I think that it would be nice to add build execution time to a final report.

So it will look like this:

--- Final status ---
serial flow: [
   serial flow: (
      job: 'TDSS_Update' SUCCESS - 1m 30sec
      job: 'TDSS_Update_adapters' SUCCESS - 30sec
      job: 'TDSS_Update_eod' SUCCESS - 48sec
   }
  job: 'TDSS_Results' SUCCESS - 5 min 34 sec
]

Dump flow

To diagnose changes in complex flows, it would be helpfull to be able to dump a flow, wihtout executing it.

Output options could be pretty-print like in normal run output, and something that was easy to machine parse.

Jenkinsflow doesn't work if Jenkins is not served from "/"

Hi, Lars

I have Jenkins served on "http://somehost/jenkins/", running under Apache. I've done upgrade to latest version and now nothing works because jenkinsflow asks Jenkins as if Jenkins in served from "http://somehost/".

Jenkinsflow returns SUCCESS when flow has failed

Hi, Lars

One of the jobs in flow has failed, but the job, that runs flow itself shows that flow failed, but still returns success. How do I fail flow job when flow has failed?

--- Final status ---
serial flow: [
   serial flow: [
      job: 'JOB_1' SUCCESS
      job: 'LONG_JOB' FAILURE  http://jenkins/jenkins/job/LONG_JOB/208/console
      job: 'JOB_2' UNKNOWN - IDLE 
   ]

   parallel flow: (
      serial flow: [
         job: 'JOB_3' UNKNOWN - IDLE 
         job: 'JOB_4' UNKNOWN - IDLE 
      ]

      serial flow: [
         job: 'JOB_5' UNKNOWN - IDLE 
         job: 'JOB_6' UNKNOWN - IDLE 
      ]

   )

]

Finished: SUCCESS

Note that flow failed, but jenkinsflow still returns "SUCCESS" instead of "FAILURE".

Is there something I miss?

Demo scripts require proxytools to be installed

Hi, Lars

I tried to run demos and found that they require proxytools package, which is listed as test dependency only. I think that demos shall run either w/o that package or that package have to be listed as normal dependency.

Method to get flow results

Hi, Lars

Another enchancement idea. Imagine that I want to get build results and timings in some report. For that I would like to call some method of jenkinsflow, to return current flow state.

It is impossible to do so now because any of the methods that may have that information are simply printing it.

Another possibility of doing that is to register fake job invocation...

Put sphinx generated documentation to ReadTheDocs

It would be nice to have documentation to be available on ReadTheDocs.com or on PythonHosted.com - AFAIK they both support Sphinx generated docs and both are free.

How to schedule pipeline even if some jobs are running?

Hi, Lars

I have big pipeline, and I want to start running it even if some jobs from previous execution are still running.

I know that once execution will come to those jobs, they will be finished already and nothing will be out of sync.

Is there a parameter to do that?

Thanks!

Flow callback function

Hi, Lars,

Another suggestion: I have lenghty subflow, and I want to send email once that flow have finished. If I add email function inside with serial(...) - it will be called right when flow is parsed. So I have to make send_email job and call it from flow. Kind of inneficient.

What I suggest is to have an ability to register callback functions with the flow:

with serial(...) as main_flow:
    main_flow.on_success(some_callable)
    main_flow.on_failure(some_other_callable)
    main_flow.invoke('job1')

That way I don't have to do a separate job and can do interesting things from the same script.

Thanks!

Aleksey

Make it easier to see job status on failure

When a flow fails, it can be hard to diagnose which jobs did not get run and if multiple jobs failed.

To make this easier - I propose that on failure the job flow (which is pretty-printed at the start of the run), is re printed, in pretty format, but including job status:

serial flow: [
  parallel flow: (
     job: a_job_name: SUCCESS
     job: b_job_name: FAILURE
  )
  job: c_job_name: NOT_RUN
]
